Side sill assembly for a vehicle

Abstract

A side sill assembly for a vehicle includes a side sill inner, a side sill outer connected to an outer side of the vehicle from the side sill inner, and a reinforcement member in an internal space between the side sill inner and the side sill outer. The side sill assembly also includes a floor panel having a side end portion connected to the side sill inner. A cross-member is installed on an upper surface of the floor panel in a longitudinal direction of the vehicle, and a connection member connects the cross-member with the side sill inner. A lower end portion of the reinforcement member is positioned within a predetermined length from an upper end portion of the internal space. The connection member is disposed at the same height as an upper surface of the reinforcement member from the ground of a reference height.

         8 . The side sill assembly of  claim 1 , wherein a battery mount, to which a battery side frame is fastened, is installed on a lower surface of the side sill inner, and wherein an upper end portion of the battery mount is spaced apart from a lower surface of the reinforcement member. 
     
     
         9 . The side sill assembly of  claim 1 , wherein the reinforcement member is bonded to an inner surface of the side sill inner with an adhesive. 
     
     
         10 . The side sill assembly of  claim 1 , wherein the reinforcement member is fastened to an inner surface of the side sill inner with a fastening bolt. 
     
     
         11 . The side sill assembly of  claim 1 , wherein a support is fixed to an inner surface of the side sill inner and is configured to support a lower surface of the reinforcement member. 
     
     
         12 . The side sill assembly of  claim 1 , wherein the reinforcement member is extruded and has a rib in a height direction of the vehicle. 
     
     
         13 . A side sill assembly for a vehicle, the side sill assembly comprising:
 a side sill inner;   a side sill outer connected to an outer side of the vehicle from the side sill inner;   a reinforcement member in an internal space between the side sill inner and the side sill outer;   a floor panel having a side end portion connected to the side sill inner;   a cross-member installed on an upper surface of the floor panel in a width direction of the vehicle; and   a connection member connecting the cross-member separated from an end portion of the connection member with the side sill inner,   wherein a lower end portion of the reinforcement member is positioned within a predetermined length from an upper end portion of the internal space, and   wherein the connection member and an upper surface of the reinforcement member are disposed on the same virtual straight extension line to support the reinforcement member.   
     
     
         14 . The side sill assembly of  claim 13 , wherein there is a predetermined distance between an end portion of the cross-member and the side sill inner. 
     
     
         15 . The side sill assembly of  claim 13 , wherein the cross-member includes one or more convex portions and one or more concave portions repeated and alternatingly extending in a longitudinal direction of the vehicle, and
 wherein the reinforcement member is bonded to an inner surface of the side sill inner with an adhesive.   
     
     
         16 . The side sill assembly of  claim 13 , wherein a seat mounting bracket connects an upper surface of the side sill inner with the cross-member and is installed upward from the connection member. 
     
     
         17 . A side sill assembly for a vehicle, the side sill assembly comprising:
